drm/buddy: Fix the range bias clear memory allocation issue
Problem statement: During the system boot time, an application request
for the bulk volume of cleared range bias memory when the clear_avail
is zero, we dont fallback into normal allocation method as we had an
unnecessary clear_avail check which prevents the fallback method leads
to fb allocation failure following system goes into unresponsive state.
Solution: Remove the unnecessary clear_avail check in the range bias
allocation function.
v2: add a kunit for this corner case (Daniel Vetter)
